Like similar flights by Boeing and Lufthansa, the aircraft was powered by a mix of petroleum and biofuel. Now the National Research Council of Canada (NRC) has removed the fossil fuel component completely with the first flight of a civil jet powered by 100 percent unblended biofuel. In the milestone flight over Ottawa on October 29, the twin engines of a specially equipped Dassault Falcon 20 business jet were powered by a biofuel derived from oilseed crops. The Falcon 20, with NRC pilot Tim Leslie at the controls, was tailed by a T-33, which collected data on the emissions generated by the biofuel-powered aircraft. NRC researchers will use the information gathered during the flight to gain a better understanding of the environmental impact of biofuel.
